IMPROVEMENT IN VAPR-BURNERS.

Specification forming part of Letters Patent No. 151,040, dated May 19, 1874; application filed January To all whom it may concern:

Be it known that I, J osIAH F. MARSH, of Dubuque, county of- Dubuque and State of Iowa, have invented certain Improvements in Vapor-Burners, of which the following is a specification My invention relates to vapor-burners supplied by the volatilization of a liquid contained in a reservoir, and connected directly with the burner; and consists in the use of a double tube for supplying the vapor directly to the burning-vents, thus supplying the vapor under diii'erent pressures to the lateral vents and jets, thereby insuring the perfectcombination i of the two flames, giving one compact and steady llame.

Figure l is a longitudinal section of the burner. Fig. 2 is an elevation of the upper part, showing the lateral vents and jet. Fig. 3 is a plan and section of the perforated disk. Fig. 4, is a plan and longitudinal section of the cap.

Like letters represent like parts.

A and B represent the supply-tubes, which have usually been made of a uniform bore. a and b represent contractions in the bore of these tubes, designed to arrest any undulatory motion in the liquid, and thus secure a uniform ilow to the-burner. These contractions may be made to any degree requisite for the accomplishment of this purpose. C is a disk under the cap D, perforated with a number of small holes, c c, each being smaller than the hole d in the cap, and whose combined area is greater than that of d. Their effect is to stop any4 solid particles which would not pass through d. If one or more of these holes c c should become clogged there would still pass a suiiciency of vapor to supply the burner.

The number of holes in the perforated disk G may be increased or diminished at pleasure.

Heretofore the lateral burning -vents and jets have been supplied directly from the same tube, the result being that, under high pressure, the iiame from the lateral vent g burned radially and did not unite with the jot.

To obviate this, I insert a tube, E, in the burner, leaving a space around it within the burner. This tube supplies vapor directly from the supply-tubes to the jet, and through the orifices c to the chamber G, with which the lateral4 vents directly communicate. rIhe orifices c being small compared withV the combined area of the vents g, it follows that however high the pressure in the tube E the pressure at the vents g will be low, thus securing the rising of the flame, and its combination with the jet flame to form an even and steady light.

In a vapor-burner, the chamber Gr, having in its upper part the lateral burning-vents g, and having within it the burning-tube E, with theinteriorof whichit communicates by means of orifices in said tube, as and for the purposes described.
